Finished the thermionic today, housed it up plugged it up nothing! flip it over and realize I never put the chips in the sockets! So I install the chips and plug it in again and still nothing, pop it out of the enclosure and survey the board with magnifier and find I missed pin 7 on IC 1, solder that up put it back in the house and works and sounds great after tweaking the trim pot, I guess it's time I looked into one of those head gear magnifiers!
